1. Trailer Type

Determining how you plan on using your trailer is the first step in selecting the best trailer for your family. Trailers can convert to basic and deluxe strollers, high-end joggers, and can even be fitted with skis for cross-country use. Based on their ability to convert, we’ve sorted trailers into three main types: Trailer Only, Trailer + Jogger or Stroller (jog or stroll, not both) and Multisport Trailers (options for stroll, jog and ski).

MULTI-SPORT: Top of the line trailers that excel as bike trailers, and offer conversion kits to convert to joggers and/or strollers. Multi-sport trailers offer the most features, provide the smoothest overall ride, and start at $400. Burley and Thule Chariot are the most popular brands of multi-sport trailers.

  • Best For: Families who want the highest-quality bike trailer OR active families who regularly use their bike trailer as a stroller or jogger.
  • Conversion Kits: All multisport trailers come with a trailer arm. Most models also come standard with a stroller kit, while jogging kits are usually an upgrade.  Burley, Thule and Croozer trailers offer cross-country ski kits as well.
  • Our Top Picks: Thule Chariot Cross 2, Burley D’Lite X

TRAILER + JOGGER or STROLLERBike trailers that come with either a stroller wheel or a jogging wheel attachment. These trailers offer less comfort features (i.e. padded seats, suspension, recline) for the riders as compared to multi-sport trailers. Popular brands include InStep, Allen, and lower-end Burley and Thule trailers.

  • Best For: Parents that will use the trailer primarily as a bike trailer, and occasionally as a stroller or a jogger.
  • Our Top Picks: Thule Coaster XT, Burley Honey Bee

TRAILER ONLY: Dedicated bike trailers. Stroller and jogger attachments are not available for these trailers.  Standard trailers range from $100 to $400, based on overall quality.  Lower-end models provide the bare basics in trailers with NO comfort features.  Higher-end models offer larger wheels and superior quality, but not suspension or conversion kits.

  • Best For: Families who do NOT plan on using their bike trailer as a stroller or jogger.
  • Our Top Pick: Burley Bee

Trailer Type: Stroller Attachments

The type of stroller available on trailers varies widely. In fact, the most common complaint about trailers is in regards to their stroller attachments.  If you plan to use your trailer as a stroller, be sure to purchase a trailer that converts to the type of stroller you want.   The five main types of strollers are outlined below and are also listed in our bike trailer product filter tool.

Attached Swivel Stroller Wheel: A small, plastic swivel wheel is attached to the trailer arm. It flips up and out of the way when in bike trailer use and flips down for use as a stroller.  When in use as a stroller, the trailer arm sticks out about 1.5 feet past the cab of the trailer and is therefore not ideal for crowded areas.  Examples include the InStep Sierra Double and the Burley Honey Bee.

The quality of this set-up is very basic on cheaper trailers like InStep or Schwinn, but functions very smoothly on higher-end trailers. This style of wheel comes standard on all Burley trailers that convert to strollers.

Stationary Jogging Wheel: Jogging wheels are designed to track straight while running, so their front wheel does NOT swivel.  A true jogging wheel is also at least 10″ in diameter and is pneumatic (air-filled) to provide smooth rolling.  To turn a jogging trailer, you must push down on the back wheels and pivot the trailer while the front jogging wheel is in the air.  All multi-sport trailers come with or have the option to purchase a jogging wheel.   Examples include the Allen SST (single), and the Burley Encore X.

Dual Swivel Stroller Wheels: This is the most functional and easy-to-use stroller type.  Two small, plastic wheels attach underneath the front of the trailer body.  Since the wheels are tucked in, it makes for easy steering and maneuverability.  Thule Chariot models come standard as a four-wheeled stroller, and most Burley trailers offer it as an upgrade.

Single Swivel Stroller Wheel: Very similar to the dual swivel stroller, but only comes with one stroller wheel, creating a three-wheeled stroller.  Pushes smooth and easy, but is not as maneuverable as four wheels when on uneven surfaces. Our top choice in this category is easily the exceptional Hamax Outback  This style also comes standard on all Croozer models.

Lockable Single Stroller Wheel (not shown): A single front swivel wheel that can be locked to prevent swiveling. Only available on lower-end trailers.  Available on Aosom 3-in-1.

2. Budget

Trailers range from under $100 to over $1,000, and in most cases, the quality and performance of a trailer are reflected in its price.  Higher-end trailers provide the most features and offer a smoother ride for parent and child, but can be heavy on the pocketbook.

Lower-end trailers are sufficient for many families riding on paved surfaces but lack many safety and comfort features offered by mid-range and higher-end trailers. Top quality brands include Thule, Burley, Croozer and WIKE. You can view and filter through trailers in all price ranges on our Bike Trailer Product Filter Tool page.

3. Size of Trailer

SINGLE OR DOUBLE CAPACITY

Single Trailers: Generally lighter, narrower, and more affordable, but offer less storage overall.  If you plan on carrying only one rider, a single trailer is generally always your best bet. Our favorite high-end single trailer is the Thule Cross, while the Burley Minnow is a great mid-range option.

Double Trailers: Can carry one or two riders (max capacity is generally 80 to 100 lb.) and offer more storage. However, they are heavier, wider, and can be more expensive.  Double trailers are best for growing families, but remember that due to changes in stroller regulations, center buckles are no longer available in double trailers for single riders.  As a result, a single child must sit to one side of the trailer.  With a single trailer, they can sit in the center, which is generally more comfortable. Our top pick in double trailers is the Thule Chariot Cross 2 or the Burley D’Lite X.

INTERNAL CABIN DIMENSIONS

Overall Cabin Size: The internal cabin dimensions of trailers vary greatly. A difference in a few inches can provide much-needed headspace and shoulder space for riders, especially for older and/or taller riders.

The Burley Bee is exceptionally tall, while the Burley D’Lite X has bowed out sides for more shoulder space for taller riders. If you have older/taller/larger kids, Hamax and WIKE offer superior internal space.

Shoulder Room: Internal shoulder width of double strollers (width of the trailer at the child’s shoulders, not the seat width) varies from 22″ to 25.5″ depending on brand. Burley’s high-end D’Lite trailers are unique in that the sides of the trailers bow out to provide additional shoulder room for riders.

Head Room: The inside height of the trailer (seat to top of cabin) can vary from 23″ to 30″. Several Thule trailers, like the Thule Chariot Lite, provide almost 27″ of headroom, while WIKE trailers provide even more at 30″.

Weight Capacity: Smaller, lower-end trailers have a lower total weight capacity of 80 lb., while higher-end trailers can carry 100 lb. (including cargo).

4. Type of Seat

If you’re hauling two kids, the strength of the seat is essential to prevent them from sliding into one another.

Hammock-Style Seats: Found on lower-end trailers, the seat is created by stretching a thick piece of fabric between the sides of the trailer. The seat is sometimes supported by nylon straps. The straps loosen with time, causing two kids to be squished together.  Hammock-style seats are more problematic for double riders versus single.

Not all hammock-style seats are created equal, however. Hammock seats on Burley and Thule trailers are certainly better and offer more support than those found on entry-level InStep trailers.

Bench-style Seats: Found on high-end trailers, the seat is a padded bench that prevents sagging.  These supportive seats are more comfortable overall and also provide more leg room for riders.

Buckles and Harnesses:  For extra comfort on the go, higher-end trailers also provide padding around the buckle and the shoulder straps, while lower-end trailers usually do not.

 5. External Covers & Venting

Plastic Rain Covers: While riding in the rain is rarely someone’s intention, keeping your child dry and warm is a concern for many that live in wet climates.  Almost all trailers come with a permanently attached rain cover that rolls up when not in use. Rain covers on lower-end models secure with elastic bands while mid and high-end models often secure with a zipper.

Burley trailers – based out of damp Portland, Oregon – provide the best weatherproofing with rain covers attached with zippers on their Encore, D’Lite, and Cub models.  The plastic covers on all Burleys can be unzipped at the bottom to provide some venting to prevent fogging, and rolled up when not in use.

Burley Encore X bike trailer rain cover

Thule’s lower-end and mid-range Coaster, Cadence, and Cheetah XT models have rain covers that secure via Velcro, while the high-end Lite and Cross models come with an entirely removable rain cover secured by elastic bands.  Thule’s removable rain cover encompasses the top and sides of the trailer for superior protection from the rain, wind, and cold.

Canopy/Sunshade: To keep the glaring sun out of a child’s eyes, high-end Thule, Burley, Hamax and Croozer models come with sunshades.  Burley’s system is built-in and slides up and down on the D’Lite and Cub, but is stationary on the Burley Encore.

Thule’s high-end sunshade snaps on and off and slides up and down the front metal rails of the trailer.  Mid-range models like the Chariot Cheetah XT are shorter and act more like a visor.

Croozer’s sunshade is available as an upgrade, is removable, and slides up and down on the internal frame. The Hamax Outback comes standard and is height adjustable with hook and loop fasteners.

Windows: The side windows on all trailers are plastic.  UV-blocking windows are available on many mid to high-end trailers. Vented side windows are no longer available on any trailers (previously available on the Thule Cougar and CX).

6. Bottom of Trailer

The bottom of most trailers (where kids rest their feet) is made of the same nylon fabric as the rest of the trailer.  The thickness of the fabric varies from brand to brand. Lower-end trailers, such as the InStep Sierra, use thin fabric which quickly wears with time, while higher-end Thule trailers use thicker versions of the same type of fabric.

For increased durability, Burley offers a hard plastic bottom on their Cub, while other brands, like Hamax, offer a rubberized bottom.  While practical, these thicker surfaces increase the weight of the trailer.

The new Burley D’Lite X comes standard with a removable rubber floor mat that makes cleaning your trailer so much easier. It’s also available as an upgrade for all their other double trailers.

7. Storage

All trailers have a storage area behind the seat to store kid and trip essentials. Most trailers provide plenty of room for jackets, a diaper bag, lunches, basketball-sized balls and much more.  Large, stiff items, like a small cooler, rarely fit in the trunk space and if they do, they tend to poke into the backs of the child riders.

The shape of the trailer greatly determines the amount of storage space available. Burley’s spacious, flat-bottomed storage area is larger than most and is excellent for carrying things like scooters after you’ve dropped the kids off at school.  The storage area on the Thule Cheetah XT, Lite and Cross is significantly smaller but the trailer is much less bulky.

Handlebar consoles are also available for handy storage of water, keys, phone etc. while in stroller or jogging mode.  Burley and Thule both offer handlebar consoles as an upgrade.  Thule’s attaches to the frame of the trailer and remains stationary when the handlebar is adjusted or flipped for trailer mode.  Burley’s console stretches between the handlebars and moves along with the handlebar as it is adjusted or flipped.

8. Wheels & Maximum Speeds

16″ and 20″ tires are available on bike trailers.  20″ tires are worth the upgrade as they absorb bumps in the road much better than 16″ tires, resulting in a smoother ride for both parent and child.  To save on costs, trailers with 16″ tires often have plastic rims, which are prone to cracking and warping.

20″ tires on metal rims offer the best performance and are available on trailers in all price ranges.  Trailers with 20″ tires generally have a maximum recommended speed of 15 mph, while those with 16″ tires max out at 10 mph.

9. Brakes

All trailers that are sold with an option for a stroller are required to include a brake.  The types of brakes range from a simple strap around a tire to a hand brake on the handlebars.  While brakes are of minimal concern when used as a trailer, as a stroller or jogger, a well-designed parking or hand-brake can make a world of difference.

Three different footbrake types on bike trailers - wheel tab, push down, and slide across

Parking Brake: A simple nylon strap buckled around the rear tire to keep the stroller from rolling away.  These straps are not convenient to use and are found on low to mid-range trailers. A slightly better version, found on Allen trailers, entails pulling out a metal tab that presses against the tire to prevent it from moving.

Foot Brake: Similar to typical stroller brakes, foot brakes are engaged with the foot and lock the rear tires. They do not slow the trailer down like handbrakes.  Foot brakes can be found on trailers of all prices ranges and vary from pushing down with your foot, to sliding it across the base of the trailer with your foot.

Hand Brake: Designed to slow a trailer versus completely stop it, like parking and foot brakes, hand brakes can be life-savers for joggers and parents navigating hills in stroller mode.  The most universal hand brake is available as an upgrade on the Thule Chariot Lite and Cross models and can be used in stroller or jogging modes.  The Hamax Outback jogging upgrade is the only jogging kit to come with a hand brake, but activates the front jogging wheel and cannot be used in stroller mode.

10. Suspension

Suspension can make the difference between a smooth, comfortable ride, and a whiny, “I want to go home” ride.  For families sticking to smooth pavement, suspension shouldn’t be a priority, but for those riding on all-terrain surfaces, it can be a life saver.

Several different suspension systems are available, but we’ve found no significant difference in their performance.  Adjustable suspension found on the Burley D’Lite, Cub and the Thule Cross and the Hamax Outback adjust to fit all families but are particularly suited for families carrying either really light or heavy kid(s).

For the average family carrying one or two average-weight kids, the non-adjustable suspension systems found on the Thule Lite and Croozer Plus models should be sufficient.

11. Adjustable Handlebars

An adjustable handlebar greatly improves the usability of a trailer in stroller or jogger mode.  Most trailers come with at least two heights, achieved by flipping the handlebar and reattaching it to the trailer.

Higher-end trailers such as the Burley Encore X, D’Lite, and Cub and the Thule Cross and Lite, and the Hamax Outback come with a swiveling handlebar that offers multiple heights.  Swivel handlebars are ideal for couples with great differences in height.  Multiple-height handlebars can be adjusted within seconds, while dual-height handlebars take a bit longer.

12. Folding 

While all trailers fold down for easy storage, some fold down more easily and smaller than others.  If you have a small trunk or limited space, be sure to check the dimensions of the folded trailer to ensure it will fit in the space you desire.

High-end brands like Thule and Burley make folding down and transporting a trailer a breeze. Entry level brands like InStep and Allen and not as easy to fold and would make frequent transportation and re-assembly a bit of a pain. If you’re going to be transporting your trailer regularly, we highly recommend going with a high-end brand.

Quick-release wheels are also an essential feature if you plan on folding your trailer on a regular basis.  The weight of the trailer is also worth considering as lifting a trailer in and out of a car can be challenging.

13. Hitch

The design of the trailer hitch determines how smooth of a ride you and your child will have. Most trailer companies (InStep, Schwinn, Allen) use a standard hitch. High-end brands (Thule, Burley, Croozer) use their own unique designs that fit more precisely, resulting in less “give” and pull-back from the trailer as you ride.  All hitch designs sold in the US flex to allow the bike to be placed on the ground while keeping the trailer upright for easy loading and unloading.

14. Infant and Baby Inserts

While it is not recommended to haul kids less than a year old in a bike trailer, many trailers convert into excellent strollers and joggers. To provide additional support for infants and babies, Thule, Burley and Croozer offer various inserts for use in stroller mode.  The Hamax Outback is the only trailer to come standard with inserts. Lower-end trailers do not offer inserts and are not safe to use with infants and babies.

15. Non-Toxic

Babies and toddlers almost always chew on the straps of trailers. Burley and Thule trailers claim to use only non-toxic materials, but Croozer trailers are the only brand to be certified as non-toxic by an outside agency.

16. Warranty/Customer Service

No one wants to be stuck with a lemon.  If you are debating between two trailers, don’t forget to pay attention to the warranty offered by the manufacturer or the reseller.  And from our experience, Burley has superior customer service.  As a dedicated trailer company, they know how to do it right!
